Police: Man set mom aflame, held teacher hostage

FORT WORTH, Texas 
A Texas man is accused of trying to sexually assault a teacher while holding her at knifepoint after he set his mother on fire at a nearby apartment complex.

Lubbock police say George James Bradley, 32, was arrested on attempted murder, aggravated assault and attempted aggravated sexual assault charges after the Monday morning incident at the Rise Academy school.

School officials say it was a random attack. Police say after setting his mother on fire, Bradley ran to the nearby school.
